Understanding of ineffective radiation protection
Author: Jin Shuangqi, who does radiation protection.
The so-called ineffective radiation protection, Jin Shuangqi, who does radiation protection, understands it in this way, that is, your protection has no effect on radiation at all, and it is ineffective protection, which is called ineffective radiation protection. In fact, ineffective protection is impossible to do in protection, it is just how effective the protection is.
Regular ineffective protection, which means that the protection you make doesn't work. Only in which case can it be encountered? For example, if you do 20mmpb protection, the width of the middle seam is greater than the thickness of the 20mmpb protective material, and there is no protection at the seam, which does not play any role in the direct, diffraction, reflection and scattering of radiation, which means that the radiation penetrates directly through the past without any blocking. In fact, this phenomenon is not possible when it comes to protection.
Conventional decoration materials, ordinary doors and windows, and even a piece of paper can block some rays, but the ability to block and absorb rays is not strong. In the protection, the blocking and absorbing effect of the decorative material on the ray is not considered. In this case, there is no protection, which is routinely called unprotected treatment, referred to as no protection.
The effect of protection is not good, and it is not called ineffective protection. The effect of protection is not good, and it has a certain relationship with the choice of protective materials, but it has little to do with it, but it is directly related to the standards and seams you require.
For the quality of the protection effect, it is necessary to follow the requirements of the pre-assessment and EIA documents, and select the highest party standard for the inconsistency between the EIA and the pre-assessment. As long as the definite radiation conditions are given, the calculated protection standards are corrected, and there are no problems under normal circumstances. If you do it according to the standards, there will be no protection, substandard protection, and ineffective protection.
